1Synthesis of P,N-2,2'-biphenyl derivatives with central chirality显示文摘Enantiopure 2-(dicyclohexylphosphino)-1,1'-biphenyl derivatives substituted in the 2'-position by a chiral amino group were prepared.For the compound bearing an acyclic chiral chain,the key step was a Suzuki coupling between bromobenzeneboronic acid and N-Boc-iodoaniline whereas an aromatic nucleophilic substitution allowed the introduction of a chiral pyrrolidine in the 2'-position of the biphenyl backbone.The efficiency of the P,N-biphenyl pyrrolidine derivatives as ligands in Pd-catalyzed arylaminations compares well with that of DavePhos ligand.JEAN Ludovic POULIQUEN Michael BLANCHET Jérme LASNE Marie-Claire ROUDEN Jacques 2010Science China Chemistry2010,53,9:0
